Pelletizing steel mill desulfurization slag - ScienceDirect

Steel mills produce two types of slags called ironmaking slag and steelmaking slag. Slags operate as an efficient medium for metallurgical reactions and are then subjected to a suitable treatment for end use, such as cooling or quenching. Initially, at a steel mill, iron ore, flux, and fuel (coke) are added into an oxygen blast...

Slag - Wikipedia

The smelting of copper and lead in non-ferrous smelting, for instance, is designed to remove the iron and silica that often occurs with those ores, and separates them as iron-silicate-based slags. Slag from steel mills in ferrous smelting, on the other hand, is designed to minimize iron loss and so mainly contains oxides of...

Common Uses for Slag | National Slag Association

Slag's ain't Slag's. SLAG is a broad term covering all non metallic co products resulting from the separation of a metal from its ore, Its chemistry and morphology depends on the metal being produced and the solidification process used. Slags can be broadly categorized as ferrous (iron/steel) and non-ferrous (copper,...

Steel Slag - Material Description - User Guidelines for Waste and ...

ORIGIN. Steel slag, a by-product of steel making, is produced during the separation of the molten steel from impurities in steel-making furnaces. The slag occurs as a molten liquid melt and is a complex solution of silicates and oxides that solidifies upon cooling. Virtually all steel is now made in integrated steel plants using a...

Steel slag recycling - Harsco Metals & Minerals

The slag derived from stainless steel production presents particular challenges, owing to the handling of fines in its cooled state. Harsco will process Electric Arc Furnace (EAF) and Argon-Oxygen Decarburization (AOD) slag, from austenitic or ferritic grades of stainless steel. We also have solutions for complying with the...
